I totally agree with Ken. If you think about this logically making 100 CDs and giving them out is presenting the work to very few people. There are many people like me that have cover versions on YouTube which, theoretically is available to millions. If anyone is going to hounded it will be the users of YouTube (and similar) and these sites would be closed down.
Also with YouTube many of the known artists videos on there are direct copies from their CD or TV put up by fans, now that, I am sure, is a violation of copyright, and what gets done about it - NOTHING.
I am quite happy to leave my cover versions on YouTube and hand out my CDs, I think you have nothing to worry about.
